Atlantic Specialty Insurance Company, a unit of Intact Financial, is rolling out a new “Shepherd Casualty Program” targeting commercial auto and commercial general liability risks across multiple states. Recent filings show the carrier introducing new forms, rules, and rates for the program in Idaho, Nevada, New Mexico, and Wisconsin, with several filings already approved or awaiting regulatory review.

The filings provide few details on the target classes or distribution strategy, but they establish a new branded casualty platform under Atlantic Specialty’s excess and surplus lines operation, complete with customized policy forms, endorsements, and rating structures.

The program’s appearance across multiple states suggests a broader national rollout is underway, adding another specialty casualty offering to Intact’s growing U.S. commercial insurance portfolio.

As background, Shepherd raised $42 million in Series B funding this year, led by Intact Private Capital, bringing its total funding to $67 million. Founded in 2021, the construction-focused MGU has since expanded into renewable energy and says it has issued more than 1,500 policies, covering over $400 billion in insured value for more than 600 commercial contractors and asset owners.

The Shepherd launch adds to Intact’s growing support of commercial insurance startups such as Arqu, Comeryx, Coterie, and Rosella.
